Distant ­supernovas (bright dots), captured by NASA’s Hubble telescope, open new vistas into the expansion history of the early universe. As early as 9 billion years ago, a mysterious repulsive force known as dark energy is seen exerting its influence.Even weirder than dark matter—the invisible stuff constituting most of the mass of the universe—is dark energy, a myst... read full post picked by rambler 1 year ago

Astronomers from SRON Netherlands Institute for Space Research have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away. The astronomers made the discovery as part of an international team using the space telescope XMM-Newton. picked by AutumnLotus 9 months ago

Beyond snapping extraordinary pictures of faraway nebulas, the revolutionary Hubble Space Telescope has completely transformed our view of the universe since it was launched in 1990. By capturing the clearest, deepest images of the cosmos ever, Hubble has shed light on some long-standing mysteries perplexing scientists-while uncovering far deeper ones that have yet to be solved. picked by AutumnLotus 12 months ago

The Large Binocular Telescope on Mount Graham, Ariz., has taken celestial images using its twin side-by-side, 8.4-meter (27.6 foot) primary mirrors together, achieving first "binocular" light. picked by AutumnLotus 6 months ago

Cosmologists at Durham University’s world-leading Institute for Computational Cosmology (ICC) have run a series of huge computer simulations of the Universe that could help solve one of astronomy’s greatest mysteries. The results tell researchers how to measure dark energy – a force that counteracts gravity and could decide the ultimate fate of the cosmos. picked by AutumnLotus 8 months ago

Scheduled for launch in 2013, the Webb telescope is widely regarded as the premier observatory of the next decade. It is an infrared telescope, which means it senses the heat of stars and galaxies millions and even billions of light years away. picked by suebe 1 year ago

The Hubble Space Telescope has provided evidence representing a major upset for conventional theories that propose a single period for star birth. The European Space Agency said the telescope, observing globular cluster NGC 2808, has shown three separate generations of stars formed early in the cluster's life. picked by AutumnLotus 1 year ago

If participants in the Dark Ages Lunar Interferometer study have their way, a telescope on the moon will allow astronomers to see 'back in time' and study the young Universe during the first 100 million years of its existence. picked by AutumnLotus 6 months ago

Perhaps the first stars in the newborn universe did not shine, but instead were invisible “dark stars” 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter. The study calculated how the birth of the first stars almost 13 billion years ago might have been influenced by the presence of dark matter – the unseen, yet-unidentified stuff tha... read full post picked by AutumnLotus 9 months ago

Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide – two ingredients that build life-forming amino acids – in a galaxy some 250 million light years away. picked by AutumnLotus 8 months ago

About 70 percent is dark energy, and around 22 percent of the universe is made up of dark matter. Dark matter makes up a substantial part of the universe. Knowing what it is would answer a crucial question about the universe as a whole. picked by braveheart 2 years ago

Suns that exploded 9 billion years ago have helped prove that a mysterious force called dark energy was pushing the universe apart even back then, scientists reported on Thursday.

Don't expect any real answers though, we still have no idea what dark energy is. picked by donteatpoop 2 years ago

The identity of the mysterious dark matter thought to pervade the universe has eluded astrophysicists for decades. Now, for the first time a team hopes to look inside the sun for one of the prime candidates. picked by AutumnLotus 3 months ago

The two biggest mysteries in cosmology may be one. A new theory says that dark matter and dark energy could arise from a single dark fluid that permeates the whole universe. And this could mean Earth-based dark matter searches will come up empty. picked by AutumnLotus 7 months ago

By taking advantage of the unique position of NASA's Spitzer's Space Telescope millions of miles from Earth, and a depth-perceiving trick called parallax, they were able to pin down the most probable location of one such object. picked by AutumnLotus 1 year ago

"Dark Tourism" was coined to describe trips to places associated with disaster and depravity. And whether you care to admit it or not, you're a dark tourist. picked by teaya21 2 years ago

Some had hoped it might be just an illusion. But it looks like dark energy is real and here to stay, as astronomers "image" the mysterious entity in action. picked by AutumnLotus 3 months ago

Scientists don't know what dark energy is, but they observe its tugging effect, which causes the expansion of the universe to accelerate. Now they have seen this mysterious force in some of the largest known features of the cosmos, called superclusters and supervoids. picked by AutumnLotus 1 month ago
